24-8-2016 ATOCHA ESTACION, MADRID - YELLOW BELLIED SLIDER (Trachemys scripta ssp. scripta)

The yellow-bellied slider (Trachemys scripta scripta ) is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets.

Adult male yellow-bellied sliders typically reach 5–9 inches (13–23 cm) in length; females range from 8–13 inches (20–33 cm). The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the neck and yellow undersides, but the latter lack the green spots characteristic of this species. The yellow belly often has an "s"-shaped yellow stripe on its face. They also have markings shaped like question marks on their bellies. Females of the species reach a larger body size than the males do in the same populations.

Mating can occur in spring, summer, and autumn. They have polygynandrous mating behavior. Courtship consists of biting, foreclaw display, and chasing. Yellow-bellied sliders are capable of interbreeding with other T. scripta subspecies, such as red-eared sliders, which are commonly sold as pets. The release of non-native red-eared sliders into local environments caused the state of Florida to ban the sale of red-eared sliders in order to protect the native population of yellow-bellied sliders.

Yellow-bellied slider movement is highly instigated by dry seasons, where they can be found traveling terrestrially to locate a new water source. One study also found movement is also highly motivated by reproductive recruitment. Differences between male and female movements were observed. Males were more active than females in spring to the end of autumn. Males also exhibited more terrestrial and aquatic movements than females. Finally, long periods of movements were exclusively males.

Mating takes place in the water. Suitable terrestrial area is required for egg-laying by nesting females, who will normally lay 6–10 eggs at a time, with larger females capable of bearing more. The eggs incubate for 2–3 months and the hatchlings will usually stay with the nest through winter. Hatchlings are almost entirely carnivorous, feeding on insects, spiders, crustaceans, tadpoles, fish, and carrion. As they age, adults eat less and less meat, and up to 95% of their nutritional intake eventually comes from plants.

The slider is considered a diurnal turtle; it feeds mainly in the morning and frequently basks on shore, on logs, or while floating, during the rest of the day. At night, it sleeps on the bottom or on the surface near brush piles. Highest densities of sliders occur where algae blooms and aquatic macrophytes are abundant and are of the type that form dense mats at the surface, such as Myriophyllum spicatum and lily pads (Nymphaeaceae). Dense surface vegetation provides cover from predators and supports high densities of aquatic invertebrates and small vertebrates, which offer better foraging than open water.

Some common predators of the yellow-bellied slider include raccoons, opossums, red foxes, and skunks. Other than predators, yellow-bellied sliders are susceptible to respiratory infections which can cause wheezing, drooling, or puffiness in the eyes and is commonly caused by bacteria. Additionally, these turtles can develop fungal spores that can lead to shell rot, they can also develop metabolic bone disease which can stunt the growth of their shells and cause them to be more brittle and prone to damage

The lifespan of yellow-bellied sliders is over 30 years in the wild, and over 40 years in captivity.

Since yellow-bellied sliders are long-lived organisms, they require high survivorship to maintain stable populations. They are particularly susceptible to negative effects associated with anthropogenic habitat modification such as increased presence of human-subsidized predators and increased road mortality. Recruitment could also be decreased in populations in highly urbanized areas due to a decrease in habitat connectivity and potential nesting sites.

24-8-2016 ATOCHA ESTACION, MADRID - OUACHITA MAP TURTLE (Graptemys ouachitensis)

The Ouachita map turtle (Graptemys ouachitensis) is a species of turtle belonging to the family Emydidae.

This species is endemic to the United States. It can be found in Texas, Louisiana, Mississippi, Alabama, Oklahoma, Kansas, Arkansas, Missouri, Iowa, Minnesota, Wisconsin, Indiana, Ohio, West Virginia, Illinois, Tennessee and Kentucky. G. o. sabinensis exists only in the Sabine River of Louisiana and Texas. Both G. o. ouachitensis and G. o. sabinensis are freshwater riverine turtles. The G. o. ouachitensis is rarely seen on land unless it is nesting season or it is basking. 

This species' carapace features a row of low vertebral spines, and is serrated on the posterior rim. The carapace is olive, dark brown, or black in coloration with light yellowish markings with dark borders. The plastron color varies from cream to yellow and is patterned with dark lines and swirls. The body color is grayish brown to blackish and is marked with yellowish stripes.

On the head, it has light yellow spots: a rectangular one behind each eye, an oval under each eye, and a round one on each side of the jaw. In some specimens, the spot behind and the spot under the eye can combine to form a single thick "C" stain. The eye has a black stripe in the middle.

Males are significantly smaller than females. The males can grow to be as large as 5 in (12 cm) in carapace length. The females can grow to be up to 10 in (25 cm) in carapace length.

The False map turtle has a carapace featuring a vertebral row of low spines and is serrated on the posterior rim. The carapace is olive to brown in color with light yellowish markings with dark borders. The plastron color varies from cream to yellow and is patterned with dark lines along the seams in juveniles. The body color of the false map turtle is grayish-brown to blackish and is marked with light brown, yellow, or whitish stripes. The eye can be brown, light yellow, white, or green and is crossed with a dark bar. Narrow hooked marks behind the eye fuse with dorsal lines on the head and neck. Also, small light-colored spots occur below the eye and on the chin.

False map turtles live in large streams of the Missouri and Mississippi River systems, ranging from Ohio, Indiana, Illinois, Wisconsin, and Minnesota, through the Dakotas southward to southwestern Alabama, southern and western Mississippi, and Louisiana. They also occur in several other river systems of Southwest Louisiana and East Texas. False map turtles prefer rivers and large creeks with moderate currents, containing aquatic vegetation, as well as snags or floating logs. They are also comfortable in deep and swift water. They occur in oxbow lakes and sloughs but are absent from lakes, ponds, or small streams.

False map turtles are diurnal reptiles. They are avid baskers, spending many hours during the day in the sun. Basking is important to these turtles, and they may even be found on steep, slippery snags. When with other turtles, they also are very communal, sharing space and using each other for predator-watching, increasing the odds of surviving an attack. False map turtles are active from late March/April to mid-October.

24-8-2016 ATOCHA ESTACION, MADRID - RED EARED SLIDER TERRAPIN (Trachemys scripta ssp. elegans)

The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.

The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.

Invasive red-eared sliders cause negative impacts in the ecosystems they are introduced to because they have certain advantages over the native populations, such as a lower age at maturity, higher fecundity rates, and larger body size, which gives them a competitive advantage at basking and nesting sites, as well as when exploiting food resources. They also transmit diseases and displace the other turtle species with which they compete for food and breeding space.

Owing to their popularity as pets, red-eared sliders have been released or escaped into the wild in many parts of the world. This turtle is considered one of the world's worst invasive species. Feral populations are now found in Bermuda, Canada, Australia, Europe, Great Britain, South Africa, the Caribbean Islands, Israel, Bahrain, the Mariana Islands, Guam, Russia, and south- and far-east Asia. Within Great Britain, red-eared sliders have a wide distribution throughout England, Scotland, and Wales.

In Australia, it is illegal for members of the public to import, keep, trade, or release red-eared sliders, as they are regarded as an invasive species – see below. Their import has also been banned by the European Union as well as specific EU member countries. In 2015, Japan announced it was planning to ban the import of red-eared sliders, but it would probably not take effect until 2020.

Red-eared sliders do not hibernate, but actually brumate; while they become less active, they do occasionally rise to the surface for food or air. Brumation can occur to varying degrees. In the wild, red-eared sliders brumate over the winter at the bottoms of ponds or shallow lakes. They generally become inactive in October, when temperatures fall below 10 °C (50 °F). During this time, the turtles enter a state of sopor, during which they do not eat or defecate, they remain nearly motionless, and the frequency of their breathing falls. Individuals usually brumate under water, but they have also been found under banks and rocks, and in hollow stumps. In warmer winter climates, they can become active and come to the surface for basking. When the temperature begins to drop again, however, they quickly return to a brumation state. Sliders generally come up for food in early March to as late as the end of April.

23-3-2015 PENANG, MALAYSIA - ORANGE SKIMMER DRAGONFLY (Orthetrum testaceum)

23-8-2016 ROYAL BOTANICAL GARDENS, MADRID - WALL BROWN BUTTERFLY (Lasiommata megera)

Lasiommata megera, the wall or wall brown, is a butterfly in the family Nymphalidae (subfamily Satyrinae). It is widespread in the Palearctic realm with a large variety of habitats and number of generations a year.

The species lives in North Africa, Europe, the Caucasus, Asia Minor, the Middle East, western Siberia, northern Tian Shan, Dzungarian Alatau, Kazakhstan and Dzungaria.

Habitats include forest edges and clearings, shrubby areas in ravines and river valleys and sparse woodlands. It is also found in mountain habitats up to 0–3,000 metres (0–9,843 ft) above sea level.

Size: 36–50 millimetres (1.4–2.0 in)

23-8-2016 EL RITIRO PARK, MADRID - MONK PARAKEET (Myiopsitta monachus)

The Monk parakeet (Myiopsitta monachus) is a small species of true parrot in the family Psittacidae. It is native to the temperate to subtropical areas of Argentina and the surrounding countries in South America. Self-sustaining feral populations occur in many places, mainly in North America and Europe; there they live in urban areas and pose a risk to crops and even native bird species.

The Monk parakeet has bright-green upperparts. The forehead and breast are pale gray with darker scalloping and the rest of the underparts are very light-green to yellow. The remiges are dark blue, and the tail is long and tapering. The bill is orange in color.

Monk parakeets are found in Argentina and the surrounding countries in South America. Self-sustaining feral populations have been recorded in several U.S. states and various regions of Europe. They live in semi-arid savannas, and woodlands and are well-adapted to urban areas.

Monk parakeets are highly gregarious birds that live and nest in colonies. They are diurnal and spend most of the day foraging and preening each other. To get their food these energetic birds climb among branches using their beaks or may drop to the ground to pick seeds or fallen berries. At dusk, they come back to their communal roost site to sleep. Monk parakeets are very noisy. Their call is a loud and throaty 'chape(-yee)' or 'quak quaki quak-wi quarr' and they also use 'skveet' screeches.

Monk parakeets are monogamous and form strong long-lasting pair bonds. They breed between October and February. These birds build a stick nest, in a tree or on a man-made structure, rather than using a hole in a tree. They often breed colonially, building a single large nest with separate entrances for each pair. Females lay 5 to 12 white eggs which usually hatch in about 24 days. The chicks are altricial; they hatch blind and are covered in yellowish down. Both parents feed their young until they are ready to leave the nest which usually occurs at 40-50 days after hatching. Reproductive maturity is reached when young birds are 2 years old.

Monk parakeets are widespread and abundant throughout their range. They are not considered threatened, however, in some areas, these birds are often persecuted as an agricultural pest.

According to the All About Birds resource, the total breeding population size of the Monk parakeet is 20 million birds. Currently, this species is classified as Least Concern (LC) on the IUCN Red List, and their numbers today are increasing.

23-8-2016 EL RITIRO PARK, MADRID - MALLARD (FEMALE) (Anas platyrhynchos)

The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have green heads, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers.

The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.

The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.

23-8-2016 EL RETIRO PARK, MADRID - IBERIAN GREEN WOODPECKER (Picus sharpei)

Fairly large woodpecker with a green back, red crown, and broad whisker stripe (red in males, black in females). Yellowish rump shows mainly in slightly undulating flight. Unmistakable in most of range; note Eurasian Green Woodpecker’s black face patch in thin band of overlap. Inhabits open woodland, heathland, gardens, parks, and farmland with hedges and scattered larger trees. Unlike most woodpeckers, feeds mainly on the ground, including garden lawns, probing into anthills and moving with an odd, shuffling gait. Calls are loud, high-pitched, and somewhat raptor-like. Drums infrequently.

The Iberian Green Woodpecker is split from European Green Woodpecker P. viridis (Pons et al. 2011; Perktas et al. 2011).

Status is near threatened

This recently-split species is undergoing moderately rapid declines in Spain, which holds the vast majority of the population. It has therefore been uplisted to Near Threatened as it almost meets the requirements for listing as threatened under criteria A2abc+3bc+4abc.

This species is found in relatively dry open woodland, both deciduous and mixed, as well as plantations, orchards, farmland and pastures, parks and gardens and locally in grassy dunes. It requires some mature trees and clearings with adjacent grassland and is found in the lowlands and hills to mountains up to ca. 3,000 m. It lays from the end of March to June. Both parents incubate the clutch which is usually five to eight eggs. The nest is excavated at up to 10 m in a tree (del Hoyo et al. 2015). It feeds on ground-dwelling ants. Other insects are taken on the ground or in trees and occasionally fruit is taken too (Gorman 2014). The species is resident, with some local movements outside the breeding season (del Hoyo et al. 2015).

Until relatively recently the Iberian Green Woodpecker, Picus sharpie, was considered conspecific with Picus viridis and Picus vaillantii, but differs in many aspects of plumage detail and is significantly different in vocal patterns. The distribution is limited to Iberia, the Pyrenees and the extremities of southern France, occurring irregularly from Pyrénées-Atlantiques to Hérault.

In Spain, the birds inhabit dry open woodland and occur in both deciduous and mixed woodlands, plantations, orchards and farmland, parks and gardens.

They require some mature trees with nearby grassland and can be found in both lowlands, hills and mountains up to an altitude of circa 3,000 metres. Mostly these birds are resident, but there are local movements outside of the breeding season with both juvenile and altitudinal dispersal largely accounting for these observations.

The local birds will be nesting from the end of March until June and both the male and female share incubation, feeding the young and, when the young leave the nest, the brood is divided between parents until they are all independent.

Mostly they are ground feeders, and their diet will be mostly terrestrial ants along with some small invertebrates. 

Although common locally, its conservation status is listed as Near Threatened. Although no threats have been identified for this species, the population has been estimated to have decreased by 30%. At a regional level it is considered vulnerable and certainly further monitoring and research are needed.

23-8-2016 EL RITIRO PARK, MADRID - EURASIAN MAGPIE (Pica pica)

The Eurasian magpie (Pica pica) is one of several birds in the crow family (corvids) designated magpies, and belongs to the Holarctic radiation of "monochrome" magpies. In Europe, "magpie" is used by English speakers as a synonym for the Eurasian magpie: the only other magpie in Europe is the Iberian magpie. The Eurasian magpie is one of the most intelligent birds, and it is believed to be one of the most intelligent of all non-human animals.

23-8-2016 EL RITIRO PARK, MADRID - EURASIAN BLACKBIRD (FEMALE) (Turdus merula)

Common blackbirds breed in Europe, North Africa, India, and southern China. Populations in the north and east migrate to winter in Egypt and the west and southeast of Asia. Depending on latitude, Common blackbirds may be resident, partially migratory, or fully migratory. These birds live in very varied habitats, including mountainous regions and big city centers, where they inhabit open forests and forest edges, woodlands, cultivated areas, gardens, and parks if the cover is dense enough for hiding.

Common blackbirds are diurnal and eat mainly on the ground, turning the leaf litter to find the invertebrates hidden below. The bird runs for a short distance and stops suddenly to turn its head sideways to detect its prey and hops while it digs the ground with its bill to attract worms. It will feed in trees and bushes on the fruits and berries that it prefers. These birds will often take sunbaths, while flattened on grass or warm ground, with their beak open and their head inclined, and wings and tails spread. Common blackbirds are territorial, strongly defending their territory, mostly in urban areas where each pair does not have much space. Females may also fight, in defense of a good nest site. While winter food is available, Common blackbirds will stay within their territory for the year, although they will occupy different areas. Migrating birds are more gregarious, flying in small flocks and eating in loose groups at the wintering grounds.

The Common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

The adult male has glossy black plumage, blackish-brown legs, a yellow eye ring, and an orange-yellow bill. The bill darkens somewhat in winter. The adult female is sooty-brown with a dull yellowish-brownish bill, a brownish-white throat, and some weak mottling on the breast. The juvenile is similar to the female but has pale spots on the upperparts, and the very young juvenile also has a speckled breast. Young birds vary in the shade of brown, with darker birds presumably males. The first-year male resembles the adult male but has a dark bill and weaker eye ring, and its folded wing is brown, rather than black like the body plumage.

23-8-2016 EL RETIRO PARK, MADRID - EPAULET SKIMMER DRAGONFLY (Orthetrum chrysostigma)

Orthetrum chrysostigma, the epaulet skimmer, is a species of dragonfly in the family Libellulidae. It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Cameroon, Central African Republic, Chad, the Democratic Republic of the Congo, Ivory Coast, Egypt, Equatorial Guinea, Ethiopia, Gambia, Ghana, Guinea, Kenya, Liberia, Libya, Malawi, Mali, Mauritania, Morocco, Mozambique, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burundi as well as Canary Islands, Israel, and Portugal. It was recorded in the Maltese Islands in 2010. One was also spotted in Tel Aviv, Israel in August 2022.

Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, and freshwater springs. The adults prey on various flying insects. The bodies of adult males are blue, and those of young and females are yellow and brown.

Very widespread and occurs virtually throughout Africa, including North Africa. It also occurs in parts of Southern Europe and the Middle East. In South Africa it occurs virtually throughout, but is scarce in the dry central regions.

The Epaulet Skimmer is a southern European and African dragonfly. A little similar to the Keeled Skimmer of the UK, it has a narrow elongated body with central raised "keel". Above is the attractive pale blue male with turquoise eyes, but the "epaulet" marking on the thorax that gives it its name is not often clear and darkens with age.

23-8-2016 ROYAL BOTANICAL GARDENS, MADRID - SCARCE SWALLOWTAIL BUTTERFLY (Iphiclides podalirius)

Iphiclides feisthamelii, the southern scarce swallowtail, southern swallowtail or Iberian scarce swallowtail, is a butterfly found in Italy, Slovenia, southern France, Spain, Portugal, Morocco, Algeria and Tunisia. It is sometimes considered a subspecies of I. podalirius.

The larva feeds on Prunus amygdalus (almond), P. persica (peach), P. insititia (a kind of plum), P. longipes, Pyrus communis (common pear), Malus domesticus (apple) and Crataegus oxyacantha.

This species is often considered merely a subspecies of the scarce swallowtail, though recent authors are increasingly counting it a separate species. Its distribution is restricted to the Iberian peninsula south of the Pyrenees. It is very similar to the scarce swallowtail but usually a more papery white, with noticeably more kite-shaped wings and a more distinct yellow line along the costa of the forewing. Another useful but not 100% diagnostic feature is the third bar from the wing base on the forewing, which is typically blunt on the vein, not tapered to a point.

Iberian scarce swallowtails may be seen very early in the year. The first pictures on this page were taken in February in Málaga, where the species was hilltopping along with many other butterflies. They fly throughout the year in two or three broods, hibernating as pupae.

After many years being considered a subspecies of the scarce swallowtail I. podalirius this taxon can now be accepted as a full species.

Identification & Similar species: Compared to the scarce swallowtail I. podalirius, this species has a white/ grey-white rather than yellowish ground colour, but sometimes with faint yellow in the female. Markings are also darker, at least in the spring brood. The differences are subtle...

Genetalia are reportedly slightly different and there is some differentiation in mitochondrial DNA.

Distribution & Flight: North Africa, Spain and southwest France. There may be overlap with the scarce swallowtail I. podalirius in some areas particularly as these are mobile butterflies. Flies from March or April to the end of summer in multiple broods.

Habitat & Behaviour: Diverse habitats: scrub, meadows, parks, gardens, coasts to mountains.

23-8-2016 ROYAL BOTANICAL GARDENS, MADRID - EUROPEAN PIED FLYCATCHER (Ficedula hypoleuca)

The little pied flycatcher (Ficedula westermanni ) is a species of bird in the family Muscicapidae. It is found in the Indian Subcontinent and Southeast Asia, ranging across Bangladesh, Bhutan, Cambodia, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, the Philippines, Thailand, and Vietnam.

Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

The Pied Flycatcher is a small, flycatching bird, slightly smaller than a House Sparrow. The male is mostly black on the upperparts and white underneath, with a bold white patch on the folded wing. Females are browner. It's a summer visitor and breeds mainly in western areas, spending the winter in West Africa.

Breeding male is boldly pied, with a big white wing patch and white forehead spot. Female and immature are brown above, with an obvious white wing patch. In areas of overlap, compare with very similar Collared and Semicollared Flycatchers. Breeds in shady, mixed and deciduous woodland, especially with oaks. Uses a range of habitats on migration and on wintering grounds, including forest edge, open woodland, and plantation. Feeds at all levels, sallying after insects in the leafy foliage; at times, perches out on open fences. Song is a cheerful whistled series with an up-and-down quality. Calls include a sharp, bright, somewhat metallic “wit!” and a short “tsee.”
